Abstract

The present work has the purpose of studying the behavior of piles caps to support columns of complex geometry. It is evaluated if the simplified designed of columns with complex geometry, using the Strut and Tie Method, can be adopted by replacing the complex geometry of the column to a square section, a routine that is frequently used and surrounded by doubts at offices of structural engineering. Numerical analyzes were performed for three columns formats (Rectangular, L and C) and two piles caps with five and nine piles. In the analysis of the different types of geometries, it was verified that the consideration of complex geometry generated a homogeneous distribution of stresses in the piles caps, resulting a lower tension fields and consequently lower rates of reinforcement when compared with the square section equivalent. Finally, for the piles caps with complex geometry columns, it was verified that the simplification of the complex geometry column by an equivalent square section can be considered in favor of security taking into account the higher quantity of reinforcement, validating the usual routine adopted in the structural offices.
